Hey everyone, im just looking for resources or links for any good information regarding proxy servers and proxy web browsers as i have limited knowledge in this area

I will be sitting ISA server shortly as part of my MCSE but would like some background knowledge jus now!
If im correct, a web cache server such as ISA will service requests on behalf of its clients to keep its clients from bein exposed on the internet and cache these requests. Does this also require all clients browsers to be set up with a proxy script or something to ensure that all its request go through the ISA server??
Any help appreciated
